WebAug 23, 2024 · There are three steps to the passivation process. First, the metal part is thoroughly cleaned to remove substances that were left behind after machining. Without this vital step, the metal could be damaged during passivation. The second step is to submerge the metal part in a passivating nitric or citric acid bath solution for 20 to 30 minutes.
WebPassivation is a chemical process with an oxidizing agent, such as nitric acid, that creates a layer of film only a few atoms thick. It is chemically inert, so it reduces the reactivity of the stainless steel. ASTM standards A380 and A967, as well as AMS-QQ-P-35 are most often referenced for passivation. chocolate and whip creamWebFeb 11, 2024 · The passivation phenomenon and its explanation, the passive films and their structures of pure iron are briefly reviewed.
